(1.9) It is easy to picture an exact differential form in this two-dimensional case. Just picture contour curves of the function z = h(x,y). These are curves defined by z = h(x,y) = c, where the values of c ...
WebDec 27, 2012 · In this problem you shouldn't think of f as identically 0. Here's an example to think about. Suppose y=x (defining a curve). Take f(x,y)=x^2-y^2. Then f(x,y)=0 along the line y=x, but f(x,y) is not identically 0. But df=0 along the line y=x. sibley foodsWebДадим определение: диффузия в газах – процесс, в ходе которого молекулы и атомы одного газа перемешиваются с молекулами и атомами другого вещества.
